I am working with a new IBM XSeries 226 server. It worked fine with the original 80 gig drives. Upon replacing them with 2 new Hitichi 500 gig drives I get DMA timouts at random times while using the on board Intel SATA controller. I put a Promice SATA controller in the machine and everything works great. Has anyone heard of a problem with Intel controllers? Thanks in advance Richard Puga Here is the info from dmesg and atacontrol; kernel: ad3: TIMEOUT - READ_DMA retrying (1 retry left) LBA=0 kernel: ad2: TIMEOUT - WRITE_DMA48 retrying (1 retry left) LBA=324524575 kernel: ad2: TIMEOUT - READ_DMA retrying (1 retry left) LBA=3780487 kernel: ad2: TIMEOUT - WRITE_DMA retrying (1 retry left) LBA=2651511 and so on.... atapci1: <Intel ICH5 UDMA100 controller> port 0x1f0-0x1f7,0x3f6,0x170-0x177,0x376,0x14a0-0x14af at device 31.1 on pci0 ad4: 476940MB <Hitachi HDT725050VLA360 V56OA73A> at ata2-master SATA150 ad6: 476940MB <Hitachi HDT725050VLA360 V56OA73A> at ata3-master SATA150 atacontrol cap ad4 Protocol Serial ATA II device model Hitachi HDT725050VLA360 serial number VFD400R40E0EHC firmware revision V56OA73A cylinders 16383 heads 16 sectors/track 63 lba supported 268435455 sectors lba48 supported 976773168 sectors dma supported overlap not supported Feature Support Enable Value Vendor write cache yes yes read ahead yes yes Native Command Queuing (NCQ) yes - 31/0x1F Tagged Command Queuing (TCQ) no no 31/0x1F SMART yes no microcode download yes yes security yes no power management yes yes advanced power management yes no 0/0x00 automatic acoustic management yes no 254/0xFE 128/0x80
